My brakes were pulsing at slow speed when I first picked up the bike. It had 10,000km on her, and I was worried about a warped disk... but after cleaning and lubing the bobbins, the pulsing stopped. I am sure someone will correct me if I am wrong, but warped rotors will pulse at any speed, and can scare the crap out of you at high speed. If the issue is only at low speeds, or as your coming to a stop, it is my understanding that more often than not it is your bobbins that have built up crap in them and need to be cleaned and lubed. The bobbins let the disk float on the hub, and if one or more of them are "frozen" or stiff, it is like the rotor is warped. Cleaning and lubing should correct the issue. If not, then look at the rotors themselves. It's the first place to look with pulsing brakes on floating disks.
